AUTOMOBILE-LOCK.

Specification of Letters Patent.

Patented Sept. 9. i919.

Application filed March 28, 1919. Serial No. 285,753.

The" principal object of the invention is to provide means for locking the bralte lever in brakmgr position and at the same time to shut off the gasolenc supply and to break" the electric circuit.

Another object of the invention is to actu ate the foregoing n'ieans by the forward movement of a member which is adapted to be moved by the foot or hand and to provide a. spring lock for lmldii'i tg the said member in its forward position.

Still another object of the invention is to provide a small case for containiiu all the parts of the device with. means for securinpthe same to the frame of the automobile.

The invention also ot'insists in certain other features of construction and in the combina tion and arrangement of the several parts, to be hereinafter fully described illustrated in the accompanying drawings and specifically pointed out in the appended claims.

in desc-iiibinn' my invention in detail, ref-- erence will he lltttl. to the accompanying drawings wherein lilm characters denotelihe or correspondinp; parts throughout the several views, and in which Figure l is a plan view showing the dcvice in place on an automobile;

Fig. 2 isa side view of the device itself;

Fig. 3 is an end view thereof;

Fig. 4t is a horizontal section;

Fig. 5 is a like view with the parts in a different position;

Fig. 6 is a bottom view; and

Fig. 7' is a section on line 'l-l' of Fig. 4.

As shown in theseviews ll provide a one ing v1 which has a downwardly extending part 2 which is provided with the ri htangular extensions" 3 containing the ho es t for receiving the bolts for securing the casingto the frame of the automobile. As shown in Fig. 1. the casing is so situated as to be adjacent the brake lever 5 of the automobile. The end walls of the casing are each provided with an opening 6. said openings being); located adjacent one side of the casing. A locking member l is located in said casing with its ends engaging said openings. The said member is of greater len h than the casing so that its ends will project therefrom though when in retracted position its forward or lookingend will be flush with the forward end of the casing. This member is provided with a slot 8 and the casing is provided with a pin 9 which projects upwardly from the bottom of the easing into said slot. A spring 10 has one end secured to the member by a pin 11 and this other end engages said in 9. This spring normally holds the 100: member in its retracted position. The locking member is provided with a projection 12 on one side thereof which engages one of the walls of the casing to limit the rearward movement of said member. ll. handle 13 is secured to the rear end of said locking; member and projects upwardly therefrom.

The means for locking; said member in projected position consist of a bolt ll: slid ingin guideways 15 formed in the casing" by the recessed lugs 16. This bolt is located at right angles to the member and is pro-- ruled with an inclined end which is adapted to engage with either one of a pair of recesses 17 formed in the adjacent side of the locking member 7. its shown, each of these recesses is provided with a straight wall and an inclined wall so as to permit thelocking member to move forwardly without being; held by the locking; bolt, but said member will be held against rearward movement, by the straight edge of said locking bolt on gaging the straight wall of the recess. The locking bolt is normally held in -.en,o agement with one of said recessesby means of a flat spring 18 having one end engaging the studs 19 in the casinp; and its other end engaging a slot in said locking bolt. The casing includes a top 20 which is provided with an upwardly extending circular portion 21 and this portion receives the lock barrel 22 having, the keyhole 23 therein. This barrel has pivoted thereto a link 2% which has its lower end engaging the bore of a tubular stud formed on the bottom of the casing. This link passes through a slot 26 formed at Ono end of a' linlt 27. the other end of which is pivoted. to the looking bolt by a pin 28. it will thus be seen that when a key is inserted in the lock barrel and the same turned the vertical link will be turned so that the horizontal link 27 will berocked to move the locking bolt against the action of its spring and out of the recess in the locking member. As soon as the key is released the spring will return the looking bolt to normal position. It will thus be seen that it is simply necessary to move the locking member either by the hand or foot engaging the handle 13, into projected position to lock the the brake lever against movement. The forward movement of the locking member will force the locking bolt rearwardly out of engagement with the first recess 17 and then when the second recess comes opposite said locking bolt the same will spring forwardly into the recess with its straight side engaging the straight wall of the recess and thus prevent the. return movement of the locking member until a key is used to withdraw said locking bolt. When the key is inserted and the lock withdrawn, the locking member will return to its retracted position by the spring 10. As before stated, the casing is so situated that the braking lever will pass along the end thereof so that when it is in braking position and the locking member is projected the end of said member will prevent-the return oi? said lever.

I-also provide means for braking the electric circuit when the locking member is in locking position and to do this 1 form a recess in one side of the locking member and place therein a block 29 of insulating material. A spring contact 30 is located in'the casing with one end in sliding engagement with said locking member. This contact is provided with a binding post 31 whichpasses through the bottom of the casing and both the contact and post are insulated from. the casing. One of the wires of the circuit is to be connected to said post. When the locking member is in unlocking positionthe contact will engage the metal part of said member so that the circuit is completed.- through the metal parts of said casing and the automobile. is in looking position a spring contact will engage the insulated block and thus the circuit will be broken so that no sparlr is made at thespark plugs.

I also provide means for shutting off the gasolene supply when the locking member is in locking position. To do this I locate a valve chamber 32 on one side of the extension 2 underneath the casing. This chamher is provided with the inlet and outlet ports for receiving the ends of the gasolene supply pipes so that the gasolene must flow through said chamber to reach the engine. A valve 33 is located in said chamber to control the passage therefrom and the valve stem passes through the upper'part of the chamber and is provided withan arm 35 indicates a lever pivoted intermediate ends to the lower part or the casing and When the locking member intense ing one and connected with-said arm and its other end provided with the slot which receives a pin 36 carried by an arm37 which is connected with an end oi the locking member. The lever is also provided with a slot which engages the pivot pin. It will thus be seen that when the locking member is in retracted position the valve will be opened to permit the gasolene to pass to the engine, but when said member is in lockingposition the connections between the valve and member will close said valve.

When the driver is to leave his car and wishes to lock the same, it is simplynecessary to place his 'foot against the handle and push the locking member into locking position. This will hold the braking means in braking position, the electric circuit will be broken and the gasolene shut off from the engine- When the driver returns it is simply necessary vfor him to insert the key in the keyhole and turn the look when the locking member will spring back into unlocklng position and this will complete the electric circuit and turn the valve to permit the gasolene to flow to the engine. 7

The device is designed to be placed under the floor of the automobile. done it will be necessary to cut an'opening to receive the upper end of the circular enlargement and to make a slot to permit the handle to pass through.

what I claim is When this is.

1. A loclring device for automobiles, comprising a casing, a sliding member therein arranged to engage the brake lever when in its projected position, a spring bolt tor holding the member in projected position, means on the bolt for making and breaking the electric circuit and means actuated by said member for interrupting the gasolene supply to the engine.
